(If you came back due to the title change, reference post 27 to see the completed watch.)
I'm working on my first dual register chronograph, a Seiko 6138-0010 'UFO' from May of 1970. It got it all taken down this evening and found the reason why the hour recorder would not reset. It had a broken arm in the reset linkage (as seen in the lower right side of the 2nd image). Someone has been in this watch before me and has absolutely drenched everything in oil. The process of scrubbing everything by hand is about to begin, and then a few trips through the cleaning machine will be in order.
I'm not documenting each stage of this rebuild like I've done previously. I wanted to give this my full attention and not be distracted by trying to remember to document each thing as I go for the purpose of a future write-up. This is my 2nd chronograph, and first dual register. I'm pretty comfortable with the mechanics at this point, and I'll document the next one on my bench, which will be one of my all time favorite watches. A correct Seiko 6139-6005 'Resist'. This is the exact same model watch as worn by Colonel William R. Pogue in the NASA Skylab mission of 1973. It was the first automatic chronograph watch ever worn in space. Seiko made several models that looked like this with the same color dial and bezel combination. All are referred to as Pogue's, but mine is the same exact model as what Col. Pogue wore - 6139-6005 "Resist" - and is known as the 'True Pogue'. It's a grail watch of mine and I'll document it for the forum. It's a really special one.
